Faster charging times

Just posted this in another forum. Heres the link:
http://forum.xda-developers.com/showthread.php?p=19994949#post19994949

So you charged the note with it in one hour?
Isn't there a limitation on the current the charger outputs while charging?

I didn't charge the Note. I originally posted this in another section for another phone model if you follow the link. I posted the thread here cause Note owners would get benefits from this charger in quicker times. I do like this one better than Apples 2A charger. Hp's is sleeker, compact and comes with a 5ft cable.

Thanks for the info. Just found it on Amazon for $9.88.

Every phone charges slowly from PC USB port, right?
Do you think this would be safe? It's a cable that is designed for portable hard drives, to give them enough power. Maybe it would give the phone too much amperage (?)
My quick research finds that a typical PC USB port (and for sure Mac) has 500 mA power, so if you used this cable with two inputs, you'd be giving the Note 1000 mA which is basically like the wall charger, so it should be safe. What do you think?

I've used it for 4 full charges and the battery stays cool but charges fast. No problems to date. It's been a great find.

Well, i have been using the charger that came with my Galaxy tab wich is 2 amp, since atday one.
No problem at all. It charges in little more than an hour.
I also have been doing this for more than a year with mi exiphone and the charger from the Ipad.
Maybe in the long run the battery life suffers, but i haven't seen anything like that. And honestly, waiting two and a half hours to get the phone charged via regular charger and ready to go me is not an option.

Going to order one right now and give it a try.
Does anyone know of any car chargers that can charge at about the same speed?

Wow, crazy.
Would you be willing to install Battery monitor widget and show me the log file during charging? Just curious to see the rate of charge (i.e. during the start and end, as it slows down)

It is.
I also have been using the 2 amp car charger that came with the original car mount of the Galaxy tab for the note and works great.
2 amp rules!!!!

So, following the same logic - the iPad charger should fit too. I am testing it now - so far so good.

I installed the Battery Monitor Widget. It says Techno: Li-ion 1500/1500mAh. This is obviously incorrect for the Note. So can anything it says about the Note's battery be of any use?

Do the Apple 2A chargers for the iPad work for "fast charging" the Note? I know when I bought one in the hopes of fast charging my Galaxy S it didn't work. The Galaxy S just recognizes it as a regular USB charger. No matter which USB cable I use (even the OEM Samsung that came with the GalaxyS)
The charger I bought was this one from Macally, the CARUSB10 and it does not work for fast charging:
http://www.macally.com/en/Product/ArticleShow.asp?ArticleID=332
However, if I use my Samsung AC wall charger or my Wife's car charger for her Blackberry it is recognized as a "AC" charger and I get the good charging speed.

That amperage is an estimate. I guess what is more interesting the time between percentages.

[Q] LTE Nexus and a Powermat?

Anyone use a Powermat to charge their phone? it looks like the usb attachment doesn't make it register like it's charging?

I have the same problem with USB charging. Neither my PC nor my Macbook Pro will charge the phone. It says charging, but the battery continues to drain. I noticed on my mac the USB port is only providing 500mA. The plug-in charger that came with the phone says 1.0 amp (1000ma).
I have a powermat too, but you need a special back cover on the phone to get it to charge this way, even that's even going to be an option on this phone.

having an issue with some of my car chargers too, some work some don't.

I initially had problems when using the power cube as well. This was a little surprising since its output was 1A which was the same as chargers which worked well. I decided to try using a different mini to micro usb adapter than the one which comes with the power cube. Once I switched adapters, the powermat worked perfectly.

Any particular model?

You would ask that. I found the packaging and it's an Adapti. It's just a cheap adapter that I bought from the local Fred Meyer (a department store chain in the Pacific Northwest) about a year and a half ago. It also came a mini-usb to iPhone adapter.
Hopefully this helps. You should be able to find an adapter that works.

I believe the one T-Mobile sells is 2.1A, and has an additional USB port so you can charge 2 devices at 1A simultaneously

T-Mobile actually sells a 3amp now.

I want that charger, but not at the $40 price tag.

I bought 2 refurbished at&t chargers ( micro usb) on ebay for $5 from one of those daily deals offers. Been using them about 6 months now, rock solid. Charges most phones faster (imo).

I have the Kensington K33497US PowerBolt Duo in both of my cars as well as on my ZX14. It has 2 USB outlets, a 1 amp and a 2.1 amp. On trips it has no problem keeping our my phone, my wife's phone and/or wife's iPad at full charge. Note: this is with both devices in use (display on and running apps)...

That sounds like a good option for you (albeit expensive), since it sounds like you were using an apple device (the iPad) on the 2.1amp outlet and an Android device on the 1 amp outlet... but it seems that this particular charger is not the best choice for non-apple devices, based on this review. This guy sounds pretty knowledgeable on the subject, and reviewed a few different similar products too, so it's some good reading.
To summarize his reviews across some of the different products he reviewed, it seems as if he has yet to find a 2.1amp/1amp combination charger that (a) supports Android devices out of the box AND (b) can deliver the full 3.1amps at once. He seems to recommend this one (with a little modification) or this one.
Of those two, it seems like latter is a better all-around choice, especially for people who own a mix of apple and non-apple devices. From his review:
"The 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. The upside of this is the 1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus this product can support one-high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port)."
Click to expand...
Click to collapse
So, my advice is the following:
Understand the differences between the Apple protocol and the non-apple protocol (or at least understand that there is a difference)
Know what types of devices you will use with the charger
Know what protocol the charger uses, and make sure it aligns well with your planned usage
Find out whether the 2.1amp and 1amp ports will work to the full 3.1 together, or if it's capped at 2.1
Read the reviews
But, as I said, that last like I posed above seems to be a good all-around charger at a good price ($9.99 + prime shipping)

Battery Monitor Widget should do what you need. It displays the current current and charge (yes, I made that sound redundant on purpose) for the battery.

Also, as I'm thinking about this more, it seems like ANY app would really only be able to give me NET current, that is... (input)-(amount being used). That wouldn't really allow me to find out how much the charger is putting out, right?

Thank you for all the input.

Thoughts?

Yes I believe for the galaxy s3 it only shows the "estimated" amp draw of the device, which is given by that expression.
Sent from my SPH-L710 using xda app-developers app

After reading the OP on this thread http://forum.xda-developers.com/showthread.php?t=1754102 the phone will draw either 500ma or 750ma. The type of charge is determined by how the charger handles pins for the USB cable. I wonder if some of the chargers that say they provide 1+ amps have the USB port setup in this manner so that the S3 thinks it's in AC charge mode.

He was talking more about his SGS2 I think. The SGS3 is 750mA or 1A I think.

The 500mA is inline with what I've previously heard about the amount of current available over a single USB port. I re-read his post and it does sound like he's making the assumption that the S2 and S3 are the same.

Charging with External Battery Pack

I just got an Anker Astro 3E that should be able to charge our tablet up to full. The issue is that apparently Samsung devices check for Samsung approved chargers using pin voltages. This battery does not have those specific voltages so instead of charging I get a red X on my battery. Samsung Tab 10.1 users have a flashing solution from what I have read. Is there an application to disable the check or can a dev look into bypassing that?
Update:
Here's the link to the mod:

The adapters to enable charging fro many source have been available for a long time and at low cost.

I know the rated current N8000 needs to get from any adapter must be not less than 2000 mA. I don't think your charging adaptor or device offers such a feature: there are very few adaptors passing the Samsung muster. They must be specifically designed for Galaxy Tab; check yours out.
That's why a desktop PC can't charge your N8000, if you plug it to an USB port, the red X pops up right away.

Exactly. Whatever Amperage it provides, unless it is made specifically for Samsung tablet, it will not charge it without the adapter I am talking about. Links to those have been posted multiple times, do a search on eBay.

I've never had a wall charger break on me. I use older Samsung, LG and Blackberry micro-usb wall chargers without any issues. I actually only use the stock charger that came with the S3 as the micro-usb cable for my pc since I heard it's best to use the stock cable whenever you use Odin and I figure I may as well use it for phone to pc data transfers as well..

Is this charger able to charge tablets. As far as I know, some tablets needs 12V output to be charged. For example Asus Transformer prime.

I got this one some time ago for my car. It's a kit with a wall and a car charger with 2 usb outlets from energizer. It does say it's for samsungs but this has charged just about anything (iphones, ipads, other phones, etc) that also had broken chargers, has never let me down for a few years now.
Both output 5V on 1A.
Haven't found a pic from the wall one, only the car charger.

using chargers with a higher amperage may not necessarily affect the battery immensely
however negative effects may be noticed over longer periods of time (battery swelling, accelerated loss of charge)
